The transformation of valve industry should start from the following points：

       1.The market trend of cast steel valve products along with the transfer of oil development to inland and offshore oil fields, as well as the development of power industry from thermal power below 300000 kW to thermal power, hydropower and nuclear power above 300000 kW, the performance and parameters of valve products should also be changed according to the changes in equipment application fields.

       2.The urban construction system generally adopts a large number of low-pressure valves, and develops to environmental protection type and energy-saving type, that is, from the low-pressure iron gate valve used in the past to environmental protection type rubber plate valve, balance valve, metal seal butterfly valve and middle line seal butterfly valve. The oil and gas transmission engineering is developing towards pipeline, which requires a large number of flat gate valves and ball valves.

       3.The other side of energy development is energy conservation, so in terms of energy conservation, it is necessary to develop steam traps and develop them to high parameters of subcritical and supercritical.

       4.With the development of large-scale power station construction, large-diameter and high-pressure safety valves and pressure reducing valves are required, as well as quick opening and closing valves.

       5.For the need of complete project, the valve supply is developing from single variety to multiple varieties and specifications. There is a growing trend that all valves required for an engineering project are provided by one valve manufacturer.

       The production and manufacturing of valve equipment has a very broad prospect in both short time and long term. Especially in the city construction, industrial development, technological innovation and globalization of these four factors, China's domestic valve industry in the future will be more international, high-end, modern development, which is also the development direction of China's domestic valve industry. The domestic valve equipment manufacturers are also in the process of constantly pursuing innovation, entering new markets, and seeking survival and development in the tide of increasingly fierce competition in the pump valve industry.
